The structuring of knowledge provides the means to organize formal knowledge into categories that facilitate its management and contribute to its dissemination. However, the formal models of knowledge classification do not allow the observation of the relationships between the different categories or the flow of this knowledge among members of the scientific community. In this work, we seek to structure scientific knowledge, represented by maps of science, considering the hierarchical structure provided by academic genealogy. We used, as a case study, all the academic descendants of Johann Bernoulli represented in the form of genealogy graph and the biographical information provided by Wikipedia following the standard developed by Mathematics Subject Classification as well as a glossary of areas of mathematics. To infer knowledge topics from mathematicians who did not have information, we used a topic propagation procedure that considers the topology of the genealogy graph. We believe that identifying and studying the flow of scientific knowledge among generations of researchers is an essential task in understanding how state-of-the-art knowledge has spread. However, in our understanding, this task was little explored by the scientific community due to the lack of data sets. We believe that this work will allow the definition of a new computational method for the study of knowledge flow. The relevance of the work lies in the possibility of discovering new information that helps to identify, analyze and structure the maps of science.
